From c1c36f73aa3085a856c7cf36d69c21d18d3ef5ac Mon Sep 17 00:00:00 2001

Subject: [PATCH] Revert "Remove all usage of @BASH@ or ${BASH} in installed
 files, and hardcode /bin/bash instead"

We need the ability to override to use `/bin/sh` here to avoid having
some bootstrap tools in a final build product.

This reverts commit 5188a9d0265cc6f7235a8af1d31ab02e4a24853d.
